4.1B parameters, published in BF16. View on Hugging Face
Set up Spark-X2.5-4BSpark-X2.5-4B is published by XHToken on Hugging Face, with 429 downloads and 81 likes to date. It's a Spark2_5ForCausalLM model built for text-generation, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for KV-cache, activations, and fragmentation. Full formula and assumptions: methodology.
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run Spark-X2.5-4B at its published (BF16) precision: 1× RTX 3080 on simplepod, at $0.070/hr per GPU ($0.070/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
